IMPROVEMENT IN HARVEST'EES.

Specification forming part of Letters Patent No. 1 37 E62 dated March25,1873.

To all whom it may concern:

Be it known that I, HIRAM M. YALE, of Goldwater, in the county of Branchand State of Michigan, have invented certain new and useful Improvementsin Harvesters; and do hereby declare that the following is a full,clear, and exact description thereof, reference being had to theaccompanying drawing and to the letters of reference marked thereon,which form a part of this specification.

The nature of my invention consists in the construction and arrangementof an adjust able pin-holder, to hold thepin in the eye of thesickle-bar of a reaper or mower, as will be hereinafter more fully setforth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure 1 is a perspective view, and Fig. 2 a side view, of my invention.

A represents the finger-bar or rather a part of the finger-bar of areaper or mower; and B is the eye of the sickle-bar running in a grooveon the same, and through which apin, a, passes to secure the pitman O tothe eye. D D represent two plates fastened to the finger-bar, each bymeans of a screw, 1), passing through a slot d, in the plate into thefinger-bar, so that said plates may be adj usted to or from the eye B,as occasion may require. Between these two plates D D is placed anotherplate, E, provided with a flange, G, at the end nearest to the eye,which flange extends along the ends of the plates D D. The other ends ofthe three plates D D and E form tubes or pipes, through which a rodpasses forming a hinge for the middle plate E, so that the same can bethrown up when desired to remove the pin a in the eye B. The pin a beinginserted in the eye connecting the pitman to the same the plate E withthe flange Gis thrown down and fastened between the plates D D bybuttons h h, and the whole attachment is then adjusted by the screws 1)b, so that the flange G will be close enough "to the head of the pin ato prevent the same from coming out, but, of course, not interfere withthe reciprocating movement of the eye.

In the old way of securing the pin there is great difficulty in removingthe same when,

as often happens, it is necessary to remove the sickle-bar, requiringtwo wrenches and a considerable time. There are, however, different waysof securing the pin, but they are all more or less insecure andobjectionable.

My invention secures the pin beyond any question, and the pin can betaken out and restored by the hand in a few seconds of time simply byturning the buttons h h and throwing the plate E with its flange upward.

When this device is applied to old machines setscrews m m are used toadjust the device more or less inclined, because of the bevel usual inthe cutter-bar; but in the manufacture of new machines they may bedispensed with by the level surface of the cutter-bar, except that theymay still be used for the purpose of adjusting the surface of the flangeG, against which the head of the pin moves.

Though this device is specially intended for use on reapers or mowers,as above described, it may equally as well be used on any other machineto hold a coupling-pin or similar device in its place.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

The adjustable plates D, in combination with the hinged plate E, flangeGr, buttons h, and set-screws m, substantially as and for the purposesherein set forth.

' In testimony that I claim the foregoing as my own ,I affix mysignature in presence of two witnesses. I HIRAM M. YALE.
